The Skorba temples are megalithic remains which have provided detailed and informative insight into the earliest periods of Malta's neolithic culture. The site was only excavated in the early 1960s, rather late in comparison to other megalithic sites, some of which had been studied since the early 19th century. The site's importance has led to its listing as a UNESCO World Heritage Site, a listing it shares with six other megalithic temples in Malta.
The area around Skorba appears to have been inhabited very early in the Neolithic period. When the eminent Maltese historian Sir Temi Żammit excavated the nearby temples of Ta' Ħaġrat, only a single upright slab protruded from a small mound of debris on the Skorba site. Archeologists ignored this mound until David H. Trump excavated it between 1960 and 1963.
The remains on the site are a series of megalithic uprights (one of them 3.4m high), the lowest course of the temples' foundations, paving slabs with libation holes in the entrance passage, and the torba floor of a three-apse temple. This three-apse shape is typical of the Ġgantija phase. Unfortunately, the greater part of the first two apses and the whole of the façade have been razed to ground level.
The north wall is in a better state of preservation. Originally, the entrance of the temple opened on a court, but in later additions during the Tarxien phase, the temple's doorway was closed off, with altars set in the corners formed by the closure. East of this temple, a second monument was added in the Tarxien phase, with four apses and a central niche.
For a period of roughly twelve centuries before the temples were built, a village already stood on the site. Its oldest extant structure is the eleven metre long straight wall to the west of the temples’ first entrance. Deposits at its base contained material from the first known human occupation of the island, the Għar Dalam phase, including charcoal, which carbon analysis dated to 4850 BC.
The pottery found on the site is divided into two styles, the Grey Skorba phase distinguished by grey-colored pottery with no motifs, and the Red Skorba phase, which is exactly like the grey Skorba but colored using red ocher.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
